Bridgestone just launched their new flagship touring tyre, the Turanza GR-90, in Bangkok. The GR-90 is the successor to the critically acclaimed GR-80. Touring tyres are essentially comfort biased.
The GR-90 has Intelligently designed rounded corners, combined with ideal construction rigidity to provide superior handling over a wide range of roads. The tread design features rows of low and high-angle winding grooves and flexible construction to deliver outstanding traveling dynamics and better water dispersion. This leads to a higher level of safety and comfort.
The GR-90 proved to be incredibly silent on rough road conditions as compared to the GR-80 at the media launch.
My Civic 2.0 used to run on a set of GR-80 some 3.5 years ago. The tyres are decent with acceptable grip and good comfort level. My only complaint about the GR-80 is the soft sidewall, making the front tyres appear under inflated even though I pumped up to 250 kPa. I hope that the GR-90 will come with a stiffer sidewall.
